Ivf immature and post-mature eggs what does this mean and how can it be prevented? By dr. Geoffrey sher on 16th april 2018 one commonly hears patients undergoing ivf report that they had too many immature eggs, and inferring that had more time been allotted to ovarian stimulation and the administration of the trigger shot been delayed by a day or more, this might not have happened. Ivf image of a mature egg on the day of egg retrieval we call this the metaphase ii, or m2 stage the presence of the polar body (red arrow) shows that the egg is mature picture of a very immature egg at the germinal vesicle stage (gv) the germinal vesicle is. Number of eggs retrieved and ivf success rates according to female age. When attempting in vitro fertilization, the level of response of the ovaries varies greatly when women take the injectable fsh drugs for ovarian stimulation. This leads to a range of eggs being retrieved at the egg retrieval procedure. Before we stimulate the woman with the fsh containing drugs, antral. At least, it has very little to do with ivf success rates over 40 with donor eggs. When choosing a donor for eggs, women should choose a woman that is younger and with few health issues. Ivf success depends so much on healthy, viable eggs, that whoever you choose to donate eggs for the procedure should be in optimal health and age. Chr investigators in 2016 published a paper, where they coined the term rescue in vitro maturation (r-ivm). It describes a circumstance usually encountered in poor prognosis patients who produce small numbers of eggs and embryos and where, therefore, every egg and embryo really counts lee et al. This work in chrs embryology laboratory has, however, been. To determine the moment when each follicle of 15mm or more produces a mature egg, doctor takes a final injection, that is called hcg. For the first 36-40 hours after the hcg shot is taken, the larger eggs will go through their final maturation process. Over the years, the number of these eggs is whittled down, and egg quality begins to decline, usually in her early thirties. This decline accelerates through the late thirties and early forties, and continues until she finally reaches the end of her fertile years.   in most cases, women over 40 benefit from standard ivf and egg donation far more than treatments like mini ivf and iui that offer vastly lower pregnancy chances. In vitro fertilization (ivf) for most women looking to get pregnant with their own eggs after age 40, ivf with ovarian stimulation is the quickest and most reliable treatment. Over 70 of mature eggs will fertilise after icsi in a good lab. Approximately 18 hours after ivf or icsi, we do a fertilization check to see how many of the eggs have fertilised. It is hard to answer this questions without seeing exactly what their protocol was. However, i would recommend a mini-ivf approach for all such cases, and make sure to carry on the stimulation with clomid and every other day fsh until for sure the follicles are large enough. If the threatens premature ovulation, you can stop it with 8 micrograms of ganerelix only because the clomid is still.
